Description

Technical Field

[0001] This utility model relates to the field of sheath technology, and in particular to a single-peak sheath with a buffering function. Background Technology

[0002] Single-wave sheath is an industrial product with a specific structure and function. It is mainly used for protection and sealing, and uses elastic waves to buffer the stress on the sheath. It is widely used in various occasions that require protection and sealing, especially in electrical wiring harnesses of automobiles, motorcycles, air conditioners, washing machines, refrigerators and other appliances.

[0003] Existing technologies, such as Chinese Patent Publication No. CN222760301U, disclose a dustproof and leak-proof protective sleeve, including a single-peak dust cover. The single-peak dust cover has a large port and a small port at each end. Indicator wires are installed inside the single-peak dust cover, the small port, and the large port, and multiple indicator wires are curved. The inner walls of the small port and the large port are respectively provided with a first sealing ring and a second sealing ring for filling gaps. This invention utilizes the design of the single-peak dust cover, the small port, the large port, and the indicator wires. When a crack appears in the single-peak dust cover, the small port, or the large port, the crack depth reaches half the thickness of the single-peak dust cover, the small port, or the large port. Although it does not completely penetrate, it exposes the indicator wires. The indicator wires form a strong contrast with the black color, making it easy for maintenance personnel to observe the crack in a timely manner and replace the entire protective sleeve, thus achieving continuous protection for the star-shaped sleeve. However, this utility model only uses a single peak as a buffer for deformation at the connection point, which is not very effective. Furthermore, the indicator wire can only be displayed when the sheath has a large crack, making it difficult for maintenance personnel to intuitively understand the degree of stress deformation of the sheath.

[0004] To address the issue that single-peaked sheaths are not conducive to adequately buffering deformation at the connection and visually displaying the deformation stress and breakage, existing technologies use sheaths to protect and seal the connection, and utilize elastic peaks to buffer deformation at the connection. However, the buffering effect of a single elastic peak is generally limited, and the sheath may break when the deformation stress is large. Existing equipment is not convenient for visually displaying the stress and damage to remind maintenance personnel whether the sheath needs to be replaced, so improvements are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing single-peak sheaths are not convenient for adequately buffering deformation at the connection and for visually displaying deformation stress and breakage conditions, and to propose a single-peak sheath with buffering function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a single-peaked sheath with a buffering function, comprising a single-peaked sheath, a port one, a port two, and a buffering mechanism, wherein the port one and the port two are respectively disposed at both ends of the single-peaked sheath, and the buffering mechanism is disposed on the surface of the single-peaked sheath.

[0007] The buffer mechanism includes an inner cavity, which is opened inside the single-peak sheath. An elastic airbag is provided on the surface of the inner cavity, and an outer pipe is connected through the surface of the elastic airbag.

[0008] A sliding plate is slidably connected to the inner wall of the outer pipe, and a sliding rod is fixedly connected to the surface of the sliding plate. The sliding rod is slidably connected to the inner wall of the outer pipe. A damage line, a standard line, and a pressure line are provided on the surface of the sliding rod. A spring is sleeved and connected to the surface of the sliding rod.

[0009] Furthermore, one end of the spring is fixedly connected to the surface of the slide plate, and the other end of the spring is fixedly connected to the inner wall of the outer tube.

[0010] Furthermore, the break line, standard line, and pressure line are arranged sequentially from top to bottom on the surface of the slide bar.

[0011] Furthermore, a pointer is fixedly connected to the surface of the outer tube, and the pointer is matched with the damage line, the standard line, and the pressure line.

[0012] Furthermore, a rubber ring is fixedly connected to the surface of the outer tube, and there are two sets of rubber rings, which are respectively arranged on the inner and outer sides of the outer tube.

[0013] Furthermore, the surfaces of port one and port two are provided with sealing mechanisms, the sealing mechanisms including mounting plate one and mounting plate two, which are respectively fixedly installed on the inner walls of port one and port two.

[0014] Furthermore, both mounting plate one and mounting plate two are fixedly connected to a sealing ring, and the surface of the sealing ring is provided with an oblique groove.

[0015] Furthermore, elastic gaskets are fixedly connected to the surfaces of both mounting plate one and mounting plate two, and the elastic gaskets cooperate with the sealing rings.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] 1. In this utility model, a buffer mechanism is set up to protect and seal the connection point using a single-peaked sheath. When the connection point is twisted or displaced, causing deformation, in addition to the elastic peak itself, an elastic airbag can also be used for double buffering. In the initial state, the spring is under pressure and is in equilibrium with the air pressure inside the elastic airbag. At this time, the pointer corresponds to the standard line. When the elastic airbag is compressed and deformed, it pushes the slide plate to make the sliding rod slide out of the outer pipe and continue to compress the spring. The degree of deformation can be intuitively understood by observing the pointer and its corresponding pressure line. When the deformation is too large and the elastic airbag and single-peaked sheath are damaged, the spring rebounds and pushes the slide plate to make the sliding rod slide into the outer pipe. At this time, the spring is in a relaxed state, and the pointer is between the damage line and the standard line, reminding maintenance personnel to replace it. By setting up a buffer mechanism, after the sheath is deformed by force, the elastic peak and elastic airbag are used for double buffering, and the degree of deformation and whether it is damaged are intuitively displayed, which makes it easy to remind maintenance personnel whether a new sheath needs to be replaced, thus effectively improving the durability of the equipment.

[0018] 2. In this utility model, by setting a sealing mechanism, the sealing rings on mounting plate one and mounting plate two are used to seal port one and port two. The inclined groove allows the sealing ring to be gradually squeezed when the connecting end enters and contacts the sealing ring. With the help of the elastic gasket, the sealing ring is tightly fitted to the connecting end, improving the sealing effect. If the sealing ring is damaged, mounting plate one and mounting plate two can be disassembled and replaced separately. By setting a sealing mechanism, the combination of the inclined groove and the elastic gasket makes the sealing ring tightly fitted to the connecting end, improving the sealing effect and facilitating the individual replacement of the sealing ring, thus effectively improving the sealing performance of the equipment.

Detailed Implementation

[0026] Please see Figures 1-5 This utility model provides a technical solution: a single-peak sheath with a buffering function, including a single-peak sheath 1, port one 2, port two 3 and a buffering mechanism 4, with port one 2 and port two 3 respectively disposed at both ends of the single-peak sheath 1, and the buffering mechanism 4 disposed on the surface of the single-peak sheath 1.

[0027] The specific settings and functions of its buffer mechanism 4 and sealing mechanism 5 will be explained below.

[0028] In this embodiment: the buffer mechanism 4 includes an inner cavity 401, which is opened inside the single-peak sheath 1. An elastic airbag 402 is provided on the surface of the inner cavity 401, and an outer tube 403 is connected through the surface of the elastic airbag 402.

[0029] The inner wall of the outer tube 403 is slidably connected to a slide plate 404. A slide rod 405 is fixedly connected to the surface of the slide plate 404. The slide rod 405 is slidably connected to the inner wall of the outer tube 403. A damage line 407, a standard line 408, and a pressure line 409 are provided on the surface of the slide rod 405. A spring 406 is sleeved and connected to the surface of the slide rod 405.

[0030] The effects achieved by the above components are as follows: the inner cavity 401 is provided to house the elastic airbag 402, the elastic airbag 402 is provided as a second buffer in addition to the elastic wave crest, and increases the buffering effect on the deformation of the connection. The outer tube 403, the sliding plate 404 and the sliding rod 405 are provided so that when the elastic airbag 402 is compressed and deformed, the internal air pressure pushes the sliding plate 404, causing the sliding rod 405 to partially slide out of the outer tube 403.

[0031] Specifically, one end of the spring 406 is fixedly connected to the surface of the slide plate 404, and the other end of the spring 406 is fixedly connected to the inner wall of the outer tube 403.

[0032] The effect achieved by the above components is as follows: When the spring 406 is in a state of equilibrium with the internal air pressure of the elastic airbag 402, the spring 406 is in a partially compressed state, and the pointer 410 points to the standard line 408. When the elastic airbag 402 is deformed by pressure, the spring 406 continues to be compressed, and the pointer 410 points to the pressure line 409. When the elastic airbag 402 is damaged, the spring 406 drives the slide plate 404 and the slide rod 405 to partially slide into the outer tube 403. At this time, the spring 406 is in a relaxed state, and the pointer 410 is located between the damage line 407 and the standard line 408.

[0033] Specifically, the damage line 407, the standard line 408, and the pressure line 409 are arranged sequentially from top to bottom on the surface of the slide bar 405.

[0034] The effect achieved by the above components is as follows: the damage line 407, the standard line 408 and the pressure line 409 are arranged from top to bottom to facilitate the correspondence between the movement of the slide plate 404 and the slide bar 405 and the pressure and damage of the elastic airbag 402.

[0035] Specifically, a pointer 410 is fixedly connected to the surface of the outer tube 403, and the pointer 410 is in conjunction with the damaged line 407, the standard line 408 and the pressure line 409.

[0036] The effect achieved by the above components is as follows: The pointer 410 is set to work with the damage line 407, the standard line 408 and the pressure line 409 to visually display the pressure and damage status of the elastic airbag 402, so as to remind maintenance personnel whether the protective sleeve needs to be replaced.

[0037] Specifically, the surface of the outer tube 403 is fixedly connected with rubber rings 411, and there are two sets of rubber rings 411, which are respectively set on the inner and outer sides of the outer tube 403.

[0038] The effect achieved by the above components is that the two sets of rubber rings 411 are set to increase the sealing between the slide rod 405 and the outer pipe 403.

[0039] Specifically, a sealing mechanism 5 is provided on the surface of port 2 and port 3. The sealing mechanism 5 includes a mounting plate 51 and a mounting plate 52, which are respectively fixedly installed on the inner wall of port 2 and port 3.

[0040] The purpose of the above components is to facilitate the individual replacement of the sealing ring 53 after it is damaged.

[0041] Specifically, both mounting plate 1 51 and mounting plate 2 52 are fixedly connected with sealing rings 53, and the surface of the sealing rings 53 is provided with inclined grooves 54.

[0042] The effects achieved by the above components are as follows: the sealing ring 53 is provided to increase the sealing between the connecting end and port 1 2 and port 2 3, and the inclined groove 54 is provided to facilitate the contact and compression between the connecting end and the sealing ring 53.

[0043] Specifically, elastic gaskets 55 are fixedly connected to the surfaces of mounting plate 51 and mounting plate 52, and the elastic gaskets 55 cooperate with the sealing rings 53.

[0044] The effect achieved by the above components is as follows: the elastic gasket 55 is provided so that when the connecting end comes into contact with the sealing ring 53 and is gradually squeezed, the elastic force of the elastic gasket 55 can make the sealing ring 53 fit tightly with the connecting end.

[0045] Working principle: By setting up a buffer mechanism 4, the single-peak sleeve 1 protects and seals the connection. When the connection is twisted or displaced, causing deformation, in addition to its own elastic peak, the elastic airbag 402 can also provide double buffering. In the initial state, the spring 406 is under pressure and is in equilibrium with the air pressure inside the elastic airbag 402. At this time, the pointer 410 corresponds to the standard line 408. When the elastic airbag 402 is compressed and deformed, it pushes the slide plate 404 to make the slide rod 405 partially slide out of the outer pipe 403 and continue to compress the spring 406. The direct measurement is achieved by observing the pointer 410 and its corresponding pressure line 409. By observing the degree of deformation, when excessive deformation causes damage to the elastic airbag 402 and the single-peak sheath 1, the spring 406 rebounds and pushes the slide plate 404, causing the slide rod 405 to partially slide into the outer pipe 403. At this time, the spring 406 is in a relaxed state, and the pointer 410 is located between the damage line 407 and the standard line 408, reminding maintenance personnel to replace it. By setting up the buffer mechanism 4, after the sheath is deformed by force, the elastic peak and the elastic airbag 402 provide double buffering, and the degree of deformation and whether it is damaged are displayed intuitively, which makes it easy to remind maintenance personnel whether a new sheath needs to be replaced, thus effectively improving the durability of the equipment.

[0046] Furthermore, by setting a sealing mechanism 5, the sealing rings 53 on mounting plate 1 51 and mounting plate 2 52 are used to seal port 1 2 and port 2 3. The inclined groove 54 allows the sealing ring 53 to be gradually squeezed when the connecting end enters and contacts it. With the help of the elastic gasket 55, the sealing ring 53 is tightly fitted to the connecting end, improving the sealing effect. If the sealing ring 53 is damaged, mounting plate 1 51 and mounting plate 2 52 can be removed and replaced individually. By setting a sealing mechanism 5, the sealing ring 53 is tightly fitted to the connecting end by the cooperation of the inclined groove 54 and the elastic gasket 55, improving the sealing effect and facilitating the individual replacement of the sealing ring 53, thus effectively improving the sealing performance of the equipment.
